Subject: [PATCH V4 00/10] Add Tegra234 HTE support
Date: Wed, 22 Mar 2023 18:29:19 -0700 [thread overview]
Message-ID: <20230323012929.10815-1-dipenp@nvidia.com> (raw)
This patch series mainly adds support for the Tegra234 HTE provider. In
addition, it addresses dt binding comments which prompted code
changes in the existing HTE provider driver without breaking the
Tegra194 provider. The comments raised concern how existing code
retrieves gpio controller node
(the node is used to help namespace conversion between HTE and GPIOLIB).
To help simplify that process, new DT property is suggested which adds
gpio controller node in the HTE provider binding as phandle property. To
conlude this patch series:
- adds Tegra234 HTE provider
- modifies existing provider code to address new dt binding for Tegra234
without breaking it for the Tegra194 chip.
The V1 patch series:
- Adds tegra Tegra234 HTE(timestamp) provider supports.
- Updates MAINTAINERS file for git tree, mail list fields.
- Updates devicetree and API documentations.
- Enables HTE subsystem, Tegra194 and Tegra234 HTE providers
by default in arm64 defconfig and dts files.
The V2 patch series:
- Changes in dt bindings to remove slices property
- Adds nvidia,gpio-controller dt property
- Add GTE node for the Tegra234
The V3 patch series:
- Re-arranged patches to have dt bindings first before its usage
- Addressed review comments regarding dt bindings
The V4 patch series:
- Logically divides dt binding and tegra HTE provider patches from v3
- Maintains backward compatibilty for the Tegra194
